ADJUSTABLE GEARINGI F'OR PRINTING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 414,979, dated November 12, 1889.

Application filed February 11, 1889. Serial No. 299,433. (No model.)

To all whom it may concern.-

Be it known that 1, JOHN T. KING, of Madison, county of Dane, and State of \Visconsin, have invented a new and useful Improvementin Adjustable Gearing'for Printing-Machines, of which the following is a specification, reference being had to the accompanying drawings.

My invention is especially applicable to that type of printing-presses known as a cylinderpress, in which power is communicated through an intermediate gearing to operate the cylinder in the upper part of the press and a rocking shaft in the lower part.

The object of my invention is to secure ready and perfect means of adjustment of the intermediate gearing in such apress by which change of impression can be made and any wear which may occur may be taken up.

Hitherto the intermediate gearing above referred to has been rigidly attached to the frame of the press and the Work of changing the adjustment has been expensive, tedious, and laborious. My invention is designed to obviate this defect.

As my invention is intended to be applied to any press of ordinary construction, and as the parts of the press form no part of my invention and are not directly related thereto, I shall illustrate only such parts of a press as are necessary to clearly indicate the purpose and scope of my improvement, and describe only such parts as are included in my invention.

In the accompanying drawings, Figure 1 is a perspective View of acylinder-press with my improvement attached. Fig. 2 is an enlarged sectional View of the parts relating to my invention detached, taken in the vertical plane of the shaft E; and Fig. 3 is an enlarged perspective View of the adjustable support of, my improved intermediate gear-stud separated from the stud.

Referring to the letters upon the drawings, A indicates the side frame of a press. B indicates the gear of the cylinder-shaft, which is adjustable in the ordinary way. 0 isatwofaced gear secured to the rocking shaft D. All these parts are of usual construction,and are described, as above suggested, only for the purpose of illustrating that which is to follow.

E is a stud, preferably made of steel, upon which is secured a flange F, whichis provided with vertically-elongated slots G.

H is an oblong aperture through the pressframe A, made to receive the stud E and allow the play of -the stud within it.

I is a nut adapted to screw upon the th readed end of the stud E and draw the flange F tight against the frame A.

J is an adjusting-screw, which passes down through the upper part of the frame A nearly to the bottom of the aperture H and enters a screw-thread in the stud E.

K is a sleeve adapted to revolve upon the stud E, and issecured by means of the screws L to the intermediate gear M and by the screws L to the pulley N. The intermediate gear M, when in position upon the sleeve K, fits closely against the flange F.

O is a balance-wheel secured to the sleeve K by the screws P.

Q is a cap secured to the shaft E by the screw R, and is adapted to hold the sleeve K and the parts secured thereto properlyin position.

S is a loose pulley turning upon the sleeve K, such as is commonly used.

T are screws which pass through the slots G I in the flange F and into the frame A, and are adapted to hold the flange F and the frame A together.-

In operation, power being applied byabelt to the pulley N in the ordinary way, the pulley and the parts attached thereto are revolved. The intermediate gear M, as is obvious, operates the gear-wheels B and O. This means of communicating motion and the instruments througli which this is accomplished form no part of my invention; but it is the device for adjusting these parts one to the other which I claim to have invented.

Suppose it is desired to change the adjustment of the intermediate gear to the Wheels B and C. All that is necessary is to loosen the screws T and the nut I. Then by turning the adjusting-screwJ the stud E may be raised or lowered to a nicet-y. Then by tightening the nut and screws it can be secured firmly in the desired position.

VVhatI claim, and desire to secure by Letters Patent of the United States, is

1. As an appliance for a cylinder printing-- press, the combination of an adjustable stud with a revolving sleeve adapted to carry all In testimony of all which I have hereunto the parts of an intermediate gear, substansubscribed my name. tially as set forth.

2. As ail-appliance for a cylinder printing- JOHN T. KING. press, the combination, with the frmneA and the adjusting-screw J, of the intermediate \Vitnesses: gear-whee1 stud E, the slotted flange F, the \V. G. \VALKER, screws 1, and nutI, substantially as set forth. J. H. PALMER.
